Devices and methods for anchoring tissue
First Claim
1. A retrievable anchor having a collapsed undeployed configuration and an expanded deployed configuration, wherein the anchor has two legs having ends and wherein the legs of the anchor in both the undeployed and deployed configurations cross in a single turning direction from one end to the other end to form a loop, and wherein the anchor is collapsible from the deployed configuration to the undeployed configuration to enable retrievability.

Abstract
Anchors, anchoring systems, anchor delivery devices, and method of using anchors are described. An anchor may be a flexible anchor having two curved legs that cross in a single turning direction to form a loop, wherein the legs are adapted to penetrate tissue. The ends of the curved legs may be blunt or sharp. The anchor can assume different configurations such as a deployed configuration and a delivery configuration, and the anchor may switch between these different configurations. In operation, the anchor may be inserted into tissue by releasing the anchor from a delivery configuration so that the anchor self-expands into the deployed configuration, so that the legs of the anchor may penetrate the tissue in a curved pathway.
